Forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations of management about future events. Forward-looking statements can often, but not always, be identified by the use of words such as &#8220;plans,&#8221; &#8220;expects,&#8221; &#8220;is subject to,&#8221; &#8220;budget,&#8221; &#8220;scheduled,&#8221; &#8220;estimates,&#8221; &#8220;forecasts,&#8221; &#8220;potential,&#8221; &#8220;continue,&#8221; &#8220;intends,&#8221; &#8220;anticipates,&#8221; &#8220;believes&#8221; or variations of such words, and statements that certain actions, events or results &#8220;may,&#8221; &#8220;could,&#8221; &#8220;should,&#8221; &#8220;would,&#8221; &#8220;might&#8221; or &#8220;will&#8221; be taken, occur or be achieved. Although management believes that the expectations reflected in these forward-looking statements are reasonable, it can give no assurance that these expectations will prove to be correct. By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that will occur in the future. There are a number of factors that could cause actual results and developments to differ materially from those expressed or implied by the forward-looking statements. Such factors include, but are not limited to, the possibility that the proposed combination will not be consummated, failure to obtain necessary shareholder or regulatory approvals or to satisfy any of the other conditions to the proposed combination, adverse effects on the operating results and/or the market price of securities of the Company and/or WTW for any reason, including, without limitation, because of the failure to consummate the proposed combination, the failure to realize the expected benefits of the proposed combination (including anticipated revenue and growth synergies), the failure to effectively integrate the combined companies following consummation of the proposed combination, negative effects of an announcement of the proposed combination, changes in global, political, economic, business, competitive, market and regulatory forces, future exchange and interest rates, changes in tax laws, regulations, rates and policies, future business acquisitions or disposals, or any announcement relating to the consummation of or failure to consummate the proposed combination on the market price of securities of the Company and/or WTW, significant transaction and integration costs or difficulties in connection with the proposed combination and/or unknown or inestimable liabilities, potential litigation associated with the proposed combination, the potential impact of the announcement or consummation of the proposed combination on relationships, including with suppliers, customers, employees and regulators, and general economic, business and political conditions (including any epidemic, pandemic or disease outbreak) that affect the combined companies following the consummation of the proposed combination. The factors identified above are not exhaustive. The Company, WTW and their respective subsidiaries operate in a dynamic business environment in which new risks may emerge frequently. Other unknown or unpredictable factors could also cause actual results and developments to differ materially from those expressed or implied by the forward-looking statements. Forward-looking statements should therefore be construed in the light of such factors. You are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date made. Further information concerning the Company and its businesses, including economic, competitive, governmental, regulatory, technological and other factors that could materially affect the Company&#8217;s results of operations and financial condition, is contained in Aon UK&#8217;s filings with the SEC.

Any forward-looking statements in this communication are based upon information available as of the date of this communication which, while believed to be true when made, may ultimately prove to be incorrect. Other than in accordance with legal or regulatory obligations, neither the Company nor WTW is under any obligation, and each expressly disclaims any intention or obligation, to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise. All subsequent written and oral forward-looking statements attributable to the Company, WTW and/or any person acting on behalf of either of them are expressly qualified in their entirety by the foregoing.</p> <p style="font-family:Times New Roman;font-weight:bold;text-align:left;font-size:10pt;margin-bottom:0px;margin-top:18pt">STATEMENT REQUIRED BY THE IRISH TAKEOVER RULES</p> <p style="font-family:Times New Roman;text-align:left;text-indent:4%;font-size:10pt;margin-bottom:0px;margin-top:6pt">The directors of the Company accept responsibility for the information contained in this communication relating to the Company, the directors of the Company and members of their immediate families, related trusts and persons connected with them, except for the statements made by WTW in respect of the Company.

The requirement will continue until this offer period ends. If two or more persons <span style="white-space:nowrap">co-operate</span> on the basis of any agreement, either express or tacit, either oral or written, to acquire an interest in relevant securities of the Company or WTW, they will be deemed to be a single person for the purposes of Rule 8.3 of the Irish Takeover Rules. Under Rule 8.1 of the Irish Takeover Rules, all dealings in relevant securities of WTW by the Company, or relevant securities of the Company by WTW, or by any party acting in concert with either of them must also be disclosed by no later than 12:00 p.m. (New York time) in respect of the relevant securities of the Company and WTW on the business day following the date of the relevant transaction. Interests in securities arise, in summary, when a person has a long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an interest by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities. Terms used in this paragraph should be read in light of the meanings given to those terms in the Irish Takeover Rules. If you are in any doubt as to whether or not you are required to disclose dealings under Rule 8 of the Irish Takeover Rules, consult with the Irish Takeover Panel&#8217;s website at www.irishtakeoverpanel.ie or contact the Irish Takeover Panel by telephone on +353 1 678 9020.</p> <div></div> <p style="margin-top:1em;margin-bottom:0em"></p></div> <p style='page-break-before:always'></p> <hr style="color:#999999;height:3px;width:100%" /> <div style="font-size:10pt;width:8.5in;margin:0 auto"> <p style="font-family:Times New Roman;font-weight:bold;text-align:center;font-size:10pt;margin-bottom:0pt;margin-top:0pt">SIGNATURES</p> <p style="font-family:Times New Roman;text-align:left;font-size:10pt;margin-bottom:0px;margin-top:12pt">Pursuant to the requirement of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.</p>
